Metal-Only Lewis Pairs with Transition Metal Lewis Basas

– … The IUPAC definition of dative bonds indicates two possible methods of identifying dative bonds. The first is whether one of the atoms is an acceptor and the other atom is a donor of elecetrons. The other is if the minimum-energy rupture pathway is heterolytic. Both methods have their flaws; the first is that Lewis base fragments may act in such a way or may be unstable if not in the presence of a Lewis acid. The second being that the gas-phase minimum-energy rupture concept requires that complexes be treated computationally but very few of these complexes have been calculated….

Why We Use Metal Sheets

– For as long as people have had the means, metal has been beaten into sheets and used for architectural purposes, from roof coverings to sewer pipes. In the late seventeenth century, this hand-hammering process was later replaced by large “rotating iron cylinders” which pressed metal into flattened sheets (Simpson 31). These water-powered rolling mills allowed for more uniform sheets as well as a less laborious and time-consuming process. The sheets were allowed to be thinner, which was advantageous when creating smaller details, such as gutters and roofing….

Gods of Metal: The Band Metalica

– “Give me fuel, give me fire, give me that which I desire”, if one doesn’t know where this famous lyric has come from, the band Metallica would be the answer. Metallica is a lethal, energetic, up tempo metal band that has been around since October 1, 1981. Screeching of the guitar, double bass pedal of the drums, deep noises of the bass, and a recognizable voice, Metallica is the only band where no band could do it any better. Metallica started out slow, overcame some obstacles and is still rocking out country to country today….

Censorship and Heavy Metal Music

– By definition censorship is the suppression of words, ideas, and images that are deemed “offensive” by the general public. As in any form of media, such restrictions in music limit the artists right of free speech and the true artist value of his or her work. For instance, in the world of heavy metal, there are multiple lawsuits against Ozzy Osbourne and one major legal dispute against a band known as Gwar. Where both artists were both falsely censored by the law and wrongly accused by our society….

Heavy Metal Music: History and Misconceptions

– Heavy Metal Music: History and Misconceptions Heavy metal music has been a source of social controversy since its early beginnings. It started out as a new age form of rock. Heavy metal brought a new look and sound to rock. The early heavy metal musicians decided to tune their guitars down, increase the tempo, play guitars and drums faster, and get a more grungy sound. The musicians also decided to wear tight, ripped, black clothing, chains, spikes, and combat boots. Most people did as anyone would expect them to do when faced with something fairly new, they found it strange and looked down on it….
